This is an expression wishing the listener good luck. Any equivalent English expression will do: "Best of luck in all your endeavors", "May your every endeavor prosper", etc. The use of the character 万 (wàn, meaning "10,000"), here just means "many" or "all".

In this kind of expressions, the English equivalent word of 万 is 'million' which means 'a great/huge number of'. you will find words or phrases like: 万岁, 千秋万载, 千千万万...

Usually in wishes, though, you'd say "all" or "every" in English. Even using the large number "million" would be sort of limiting your good wishes! (Also, it's worth being clear to learners that wan4 does NOT mean "million" literally!)

万 can be more accurately translated as "myriad", which also means 10,000 but more often is used to refer to a large multitude in English; this usage is coincidentally very similar to that of Chinese 万.
